LDN240 Series are single phase DIN Rail Switching Power Supplies,
suitable for worldwide applications such as process control, heavy
duty applications, but also building automation.
These units have received excellent market approval for their high
efficiency, excellent reliability and compactness. Simple but elegant
look and ease of installation due to pluggable connectors make them
ideal for various industrial applications.
LDN240 Series are Class I isolation devices suitable for SELV and
PELV circuitry (up to 48 VDC models) and are designed to be mounted
on DIN rail and installed inside a protective enclosure.
Single phase AC input 120 / 240 VAC (with switch)
High efficiencies and in compact size
Only 63 mm width aluminum enclosure
